摘要

全球地下水资源的不断枯竭和不合理开发,造成了严重的生态环境影响,加剧了水资源短缺。因此,有效、可持续的管理是确保水资源安全和平衡的当务之急。本研究采用地理信息系统(GIS)、遥感和模糊层次分析法相结合的综合评价方法,对米河流域人工补给的适宜性进行了评价,共划分了14个主题层。FAHP是为这些层分配相对权重的关键工具,能够全面评估人工补给的适用性。研究区可分为5个适宜性等级,季节变化显著。在丰水期,该地区的评分为:5.80%,很好;35.24%,好;41.96%,中度;16.11%,贫困;0.89%,非常可怜。枯水期为11.02%(很好)、39.80%(好)、34.39%(中等)、10.39%(差)、4.39%(很差)。盆地中部地区不适合人工补给。通过分析来自29口井数据集的接收器工作特征曲线,验证了该模型的准确性。该研究为密河流域地下水可持续管理提供了科学依据,并验证了GIS和FAHP在人工补给潜力评价中的有效性。未来的研究应提高数据的准确性,以提高模型的精度,并扩展其对各种地理和环境设置的适用性。

Assessing groundwater artificial recharge suitability in the Mi River basin using GIS, RS, and FAHP: a comprehensive analysis with seasonal variations

The escalating depletion and irrational exploitation of global groundwater resources have led to severe ecological and environmental repercussions and exacerbated water scarcity. Therefore, effective, sustainable management remains urgent to ensure the security and balance of water resources. This study utilized an integrated approach that combines Geographic information systems (GIS), remote sensing, and the fuzzy analytic hierarchy process to assess the suitability of artificial recharge in the Mi River watershed, creating 14 thematic layers. FAHP is a crucial tool for assigning relative weights to these layers, enabling a comprehensive assessment of the suitability of artificial recharge. The study area was categorized into five suitability classes with notable seasonal variations. During the wet season, the areas were rated as follows: 5.80%, very good; 35.24%, good; 41.96%, moderate; 16.11%, poor; 0.89%, very poor. These percentages during the dry season changed to 11.02% (very good), 39.80% (good), 34.39% (moderate), 10.39% (poor), and 4.39% (very poor). The central basin regions were deemed less suitable for artificial recharge. The model's accuracy was validated by analyzing receiver operating characteristic curves derived from a dataset of 29 wells. This study provides a scientific foundation for sustainable groundwater management within the Mi River watershed and substantiates the effectiveness of GIS and FAHP in evaluating artificial recharge potential. Future research should improve data accuracy to increase model precision and extend its applicability to various geographical and environmental settings.
